Array substrate, display panel having the same and method of manufacturing the same
View Patent ↗In an array substrate, the array substrate includes an insulation member in each pixel area and a color filter layer that surrounds each insulation member. The color filter layer includes color filters having two or more colors that are different from each other, and a color filter is formed in each pixel area. An insulation member is arranged in each pixel area and all the insulation members include the same material. The insulation members are partially removed in each pixel area to form contact holes having the same size.
1. An array substrate, comprising:
a base substrate comprising a plurality of pixel areas to display an image;
a thin film transistor arranged in each pixel area;
a first storage electrode arranged in each pixel area;
a second storage electrode arranged on and insulated from the first storage electrode;
an insulation member covering the first storage electrode and the second storage electrode and comprising a contact hole through which the thin film transistor is exposed, the insulation members all comprising the same light-blocking organic material;
a pixel electrode arranged in each pixel area to cover the insulation member, the pixel electrode being connected to the thin film transistor through the contact hole; and
a color filter layer comprising color filters arranged under the pixel electrode to surround the insulation members and covering the thin film transistor, a portion of the color filter layer being level with the insulation members.
2. The array substrate of claim 1 , wherein the insulation member comprises the same material as a color filter.
3. The array substrate of claim 2 , wherein the color filters of the color filter layer comprise red, green, and blue filters, a color filter being arranged in each pixel area, and the insulation member comprising the same material as either the red, green, or blue color filter.
4. The array substrate of claim 1 , wherein the insulation member is positioned on the second storage electrode, and the pixel electrode is connected to the thin film transistor via the second storage electrode.
5. The array substrate of claim 4 , wherein the second storage electrode extends from a drain electrode of the thin film transistor.
6. The array substrate of claim 5 , further comprising:
a gate line arranged on the base substrate to transmit a gate signal;
a data line insulated from and crossing the gate line to define a pixel area and to transmit a data signal corresponding to the image; and
a common voltage line extending in a same direction as the gate line to transmit a common voltage,
wherein the first storage electrode is branched from the common voltage line.
7. A display panel, comprising:
an array substrate comprising:
a first base substrate comprising a plurality of pixel areas to display an image;
a thin film transistor arranged in each pixel area;
a first storage electrode arranged in each pixel area;
a second storage electrode arranged on and insulated from the first storage electrode;
an insulation member covering the first storage electrode and the second storage electrode and comprising a contact hole through which the thin film transistor is exposed, the insulation members all comprising the same light-blocking organic material;
a pixel electrode arranged in each pixel area to cover the insulation member, the pixel electrode being connected to the thin film transistor through the contact hole; and
a color filter layer comprising color filters arranged under the pixel electrode to surround the insulation members and covering the thin film transistor, a portion of the color filter layer being level with the insulation members;
an opposite substrate facing the array substrate, the opposite substrate comprising:
a second base substrate facing the first base substrate; and
a common electrode arranged on the second base substrate; and
a spacer interposed between the array substrate and the opposite substrate to maintain a cell gap between the array substrate and the opposite substrate, the spacer comprising the same material as the insulation members and being overlapped with the thin film transistor.
8. The display panel of claim 7 , wherein the spacer is positioned on an upper portion of the thin film transistor.
9. The display panel of claim 7 , wherein the color filters of the color filter layer comprise red, green, and blue filters, a color filter being arranged in each pixel area, and the insulation member comprising the same material as either the red, green, or blue color filter.
10. The display panel of claim 9 , wherein the opposite substrate further comprises a black matrix arranged on the second base substrate and between the pixel areas to block light.
11. The display panel of claim 7 , further comprising a liquid crystal layer disposed between the array substrate and the opposite substrate to adjust a transmittance of a light applied thereto.
